Back staking plan

(Back) Percentage

Stake a fixed percentage of the current bank, so stakes grow with wins and shrink with losses.

Percentage stakes a share of whatever the system's bank is right now. It compounds on the way up and protects on the way down, and the bank can never reach zero.

Parameters

Percentage To Bet: the share of the bank to stake on each bet. 2% of a £1,000 bank is £20.
No Decrease: tick it and the stake is never reduced, even when the bank falls. It still rises when the bank grows.

The sums behind compounding, and why it's the plan to move to once you trust a system, are in Staking plans for a betting bot.
